What version of Firefox actually allows you to add extensions? I'm running the most current version of Tumbleweed that ships with 144.0. Attempts to add extensions just sit there doing nothing until I close the tab. This sort of worked some time ago (I forget the version) but the inability of Firefox to allow add-ons/extensions is getting to be a joke. There are other browsers out there, ya know.

I'm having an issue wherein clicking the on-screen back button in the toolbar does not immediately navigate to previous webpage that was viewed. From my recollection and in all my years of computing, I have always understood that the original purpose of a browser's back button was to return to the page, not to reverse any scroll actions. However, someone has changed this.

The problem is that the back button isn't navigating to the previous page, but rather undoes any scroll actions that were performed on the current page being viewed. Once all scrolling is undone, it's back at the the top of page again (default scroll position). Only by clicking the back button one more time will it actually go to the previous page. However, this is not the desired behavior. The desired behavior is that clicking the back button just once should be all that is required to get to the previous page, skipping any scroll actions that were performed on the current page.

I see other articles talking about what happens when you use the scroll wheel and/or mouse buttons. That is not what I am talking about here. I'm only talking about what happens when you click the graphical back button (which looks like a left arrow) on the toolbar. It's the built-in back button in Firefox.

Does anyone know how to restore the button's original functionality?

OK when I restart firefox, or have been using it for a while, I might decide that I'd like to close a TAB or maybe even a heap of them.

Trouble is that someone has decided that when people close a TAB, the one to the right, automatically reloads.

I don't want to reload a TAB I am not currently using, I just want to close the TAB or TABS, that I am no longer using.

Stop doing this really retarded "Oh we think this is a good idea to automate things - you don't want, don't need and have not asked for, with the typical NO choose to switch it on, and NO off switch".

Seriously provide the option to turn this function on, and to turn it off.

AND up till the day this never happens, is there a switch in the about:config to turn this highly undesirable and useless function off?

Firefox open a home page when I press Esc in every page.

PS. Also you have a typo in "Explore solution" block in russian (О ззначках дополнений)

An e-banking site that worked in Firefox for years no longer works in 145.0 under Ubuntu Studio 24.04.1 This is the help page for the error I am receiving: https://support.mozilla.org/1/firefox/145.0/WINNT/en-US/connection-not-secure However, the error message I received (see attached image) is not listed there. Since the e-banking site hasn't changed in ages, I suspect instead something in one of the recent Firefox updates. The site works fine in Safari under Sequoia 15.5 on a MacBook Air, and I can login in Firefox, so I doubt that there is a problem with the site's security certificate. Since both the MacBook Air and the Ubuntu PC are on the same LAN, I also doubt any network obstruction. I haven't found a wax to get any more detailed error information and would be grateful for tips on how to do so. Meanwhile, I would like to at least change from the standart Firefox release to the ESR veersion, but find no information on how to do so. I have currently set up Firefox to be pulled from the instructions in https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended under "For Debian Trixie and Newer" How can I switch from my current Firefox under Ubuntu to an ESR release?

I have an Investors.com account and a feature they offer is a stock sector data table that shows recent performance and other information. When I try to open these tables they close immediately, but if I use my tablet with a different browser they will remain open. I believe this is a simple setting that I need to adjust, but I don't know enough to figure it out.

Password generated by the password manager is 100% numbers: no letters, uppercase letters, or symbols. Just "745848727839949". This is not a valid password. This number seems to be the same every time and is remembered even tho it hasn't been stored.

Hello,

how can i disable firefox usage hints like "Try tab groups for less clutter, more focus"?. It opens up if i open up a certain amount of tabs. Is there anything i can disable in about:config?

Thank you.

Fedora 42 x86_64, firefox 145.0

Using FontForge, I created a custom Unicode (NO 8-bit pi encoded) version of the Symbol typeface with a new font-family name.

One of the customizations, the serif versions of the "Registered Sign", "Copyright Sign", and "Trademark Sign" are available by the official Unicode codepoint. The sans-serif versions are available by the official Unicode codepoint *directly* followed by U+200B (Zero Width Space - ZWSP).

This is done with the OpenType contextual alternative feature (calt).

It works in the FontForge metrics test window and it works in Chromium and derivatives but it does not work in FireFox - either the Fedora 42 build or the generic x86_64 build from Mozilla.

I tried the CSS setting:

body { font-feature-settings: "calt" on; }

No dice. I believe that's the right CSS setting because if I change the "on" to "off" then it no longer works in chromium and derivatives, so that does seem to the be the CSS setting that controls whether or not the feature is enabled.

All my searches on the web seem to indicate the FireFox supports calt however all the examples I see are related to swashes which are enabled/disabled by a different CSS setting.

I did see some indication that some apps only allow calt for certain language scripts, typically Arabic and/or Greek and/or Latin and perhaps these legal glyphs aren't considered one of those scripts?

Does anyone know why the calt works elsewhere and not in FireFox? Yes, I tried without any extensions or plugins enabled.

The PW I am using to attempt to sync firefox to my new windows computer is in the active firefox that I currently use. I have checked it in my desktop version and also on my ipad and the PW in both are the same yet when i try to sync the new computer and put the PW in that is in both my desktop and iPad; I get msg it is wrong PW. So then I tried to get a new recovery code (can't find old one) it asks me for the PW and again; get msg it's wrong. How can it be wrong if it's the one in my current firefox that I am typing this on right now? Doesn't make any sense to me! How can the current PW in the active firefox account be incorrect when I try to sync my new computer? (I have double/tripled/quadrupled and even copied the current PW from the PW list in firefox!)

thx

I have recently encountered reproducible failures when attempting to download files or save pages to local storage. The target directory is located on a mounted NTFS file system with the options umask=007, user=root, and group=disk. My Firefox browser is running under a non-root user account that is a member of the disk group. However, I consistently receive the error message: “XXX could not be saved because the source file could not be read.”

I would greatly appreciate anyone's assistance in resolving this issue.

I am using Mozilla as my default web browswer in Unix environment. It is great... except for a particular behavior of the browser window. When I middle click (MB2) the frame of the window, it doesn't go to the background, like all my other windows. Intead it opens a new tab (when I click at the top of the window). This is very annoying becaue I use MB2 /go to background all th etime. Any idea how to change that behavior and make it consistent with my general unix preference? Here is how it looks: see attachment.

Thanks in advance.

Hi there! I find the new sidebar (on the left for me) a great addition but is there a way to reverse the "top to bottom" tabs displaying order?

Not a way to move tabs, but a setting allowing, when opening a new tab (Ctrl+t), to place (and display) the icon on top of the tabs icons pile, not at the bottom.

I get that it's the opposite of the normal reading direction, but it's rather unnatural to go looking at the bottom of the screen for recently opened tabs, IMHO.

Thanks in advance if you can address this, or show me where I can find such setting.

Best regards from France, Jc

Hello,

In multi-window browser sessions on Linux, the "Recently closed tabs" menu shows a list of URLs relevant to the parent (aka current) window, and that is both perfectly logical and highly useful. It makes it a lot easier to find that specific URL you're looking for, if not only because it increases the chance that it hasn't yet been flushed out of the recently-closed list.

I have a very distinct memory that this was the case on Mac too for the URLs showed by this menu when accessed via the "hamburger menu". I'm positive that I accessed the function via the hamburger menu rather than the faster way via the menubar for that very reason. And I just realised that it's no longer possible starting with at least v143.

With the Mac's global menu bar it would stand to reason that it presents lists that are "global" to the session, but I see no good *usability* reason that would justify *not* using window-specific lists under the hamburger menu.

One could of course argue that it's confusing and a "burden" to the user that s/he would need to remember in which window the looked-for tab once lived. But that argument would apply to all platforms, and this is supposed to be about *recently* closed tabs and one has to assume that the majority of users have no issue remembering in which window they have (or had!) a given tab open. (And that otherwise they'd be using a singe window, probably maximised to occupy the entire screen ;) ).

Hey, I am currently working on an application where I want to upload files to a server using mtls via a webapp. The upload goes to another url and server than the one where the webapp is served from. If I test the file uploading without mTLS, it succeeds, and with mTLS enabled it also works in chromium, but in Firefox I get the following error: "Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at <url> (Reason: CORS request did not succeed). Status code: (null)." on the `OPTIONS` request before the `PUT` is done. The client and the server both have a certificate from a custom CA, which I imported into firefox, along with the private key. Does someone know what the issue here might be? I am suspecting that there is some problem with firefox loading the user certificate on the preflight request?

Consider the following scenario: I want to go to "nextcloud.com", so I go to the address bar and start typing. Unfortunately, I make a mistake, and the first character I type is 'b'. Firefox then offers the autocomplete "bc.co.uk", and highlights it. I type another different letter, the added autocomplete offer is replaced with the character I added, and it will try to offer another autocomplete suggestion with all the characters I have typed so far. However, I realised the 'b' was wrong, so I press <backspace> then start typing "nextcloud.com". Of course, the backspace key now only removed the autocomplete suggestion, leaving the original 'b' I typed (so I now have "bnextcloud.com"). My question: Is there a way set configure firefox so that the key sequence 'b' followed by '<backspace>' to return the address bar to the original (empty in this example) condition? If this means turning off auto-suggest, I am happy to do that, since I don't use it anyway.

Thanks.
